OvmfPkg: Update code to be more C11 compliant by using __func__
...
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.
Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

OvmfPkg/BaseMemEncryptTdxLib: Refactor error handle of SetOrClearSharedBit
...
The previous implementation of SetOrClearSharedBit doesn't handle the
error correctly. In this patch SetOrClearSharedBit is changed to return
error code so that the caller can handle it.

OvmfPkg/BaseMemEncryptTdxLib: Add TDX helper library
...
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
Add Intel Tdx helper library. The library provides the routines to:
- set or clear Shared bit for a given memory region.
- query whether TDX is enabled.
Please be noted, there a lot of duplicated codes for Page Table
operations. These codes should be moved to a common library
(PageTablesLib) so that it is more friendly for review and maintain.
There is a new feature requirement
https://bugzilla.tianocore.org/show_bug.cgi?id=847 which is to
implement the library. After the lib is introduced, BaseMemEncryptTdxLib
will be refactored.
